RE: Does Dell Technical Support Know Anything About Their Computers?
Well, I continued to receive terrible service from Dell. I literally called 8 times to sales to try to get the proper stick of RAM. Most representatives were trying to sell me SO-DIMMS for laptops. One told me 200+ for one stick (she was clueless and looking at ECC ram), one guy told me $125 (laptop ram), couple hung up on me because I informed them how incompetent they were, and one told me they didn't make ram for my system yet (WHAT?). I finally got a lady that actually knew how to turn a computer on and gave me a 7% discount even though Alexander Saravia promised me a 10% concession they would not honor it and Alexander refused to respond to further emails.
Anyway, the board DOES run in dual channel mode. The stick of RAM I got from crucial was not stable in the system at all and routinely wouldn't boot, even though Crucial says it was the correct module. Ryzen boards do have issues with a lot of RAM since they are so new at this point though.
The Dell rep sold me a stick made my Visiontek and it's currently in the system and appears to be working fine.
As for dual channel performance. It makes a very significant difference in performance if your application needs a lot of memory bandwidth. Some games (not all), video editing, engineering and other professional applications see very significant boosts.
Dell also sells these gaming pc's with AMD APU's. With built-in graphics chips on the processor die, dual channel makes a HUGE difference in performance.
